The stock market will do that at least 2-3 times per century.

 - your market has produced one of the best residential returns in the nation for this century

Curbio may just be the greatest gift of the century for flippers.

Age of tree of course plays into it.. when you look at for instance turn of the century ( after 1908 ) SF homes built with real 2x 4 redwood with trees that were 500 to 1000 years old its just stunning material..

Owing to the trend towards smaller,  more efficient appliances and LED lighting  electrical loads I think are somewhat less than they may have been per SF like in the 70's through 2000's when everybody had incandescent lighting and big tube TVs and refrigerators, dishwashers,  etc. that used 2 or 3x as much power as modern ones.I've had a couple turn-of-century units rewired to remove K&T and failed 'BX" (flexible steel sheathed  2 wire cable)  and agree with other posters the pricing isn't that bad as long as you can find an electrician that has some experience with that kind of work,   and sometimes it might be helpful to open up some cable routes ahead of time for them to use so they don't have to do the exploratory work.   

@Greg Jeanfreau The house is a late 19th century barge board shotgun double.

I had a conversation once with a very smart Dr. who stated that this concept does not exist in all cultures and was/is more prevalent in certain cultures in centuries past.

I did 1031s, paid no tax and bought newer, nicer, more up to date properties with central air, garages and built since the turn of the century, and I don't mean 1900. 

There is a reason case shiller top residential return markets for this century have zero high initial cash flow markets.  

Just as the 1800s were New York's century, and 1900s California's century, the 2000s are Texas's century, and it is only just beginning.
